Abstract

PROBLEM TO BE SOLVED: To prevent linear or dotted stains, by laying a floor panel in which an air vent connected to the underfloor space of a free access floor is formed by cuting a carpet and a panel body, at one or more arbitrary positions in the free access floor. SOLUTION: Support legs 2 are erected on a foundation floor face at every certain distance and a plurality of floor panels 3, 3' are laid over the support legs 2 to form a free access floor. Carpets 32 are bonded integrally with an adhesive or the like on the surface of a rectangular panel body 31 to constitute the floor panels 3. Carpets 32 are bonded to the panel body 31 in the same way with the floor panel 3, in the floor panel 3'. Air vent openings 5 connected to the underfloor space of the free access floor are formed by cutting the carpets 32 and the panel body 31. Accordingly, even when a floor panel on which a carpet is laid, is used, there is no fear of linear or dotted stains at the peripheral edge of a carpet of respective floor panels, which is apt to be stained in conventional cases.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a free access floor constructed by arranging a floor panel over support legs which are erected on a foundation floor surface.

[0002]

2. Description of the Related Art In a room having a free access floor, movement of air occurs between the room and the underfloor space of the free access floor due to changes in temperature or use of a ventilation fan. This movement of air is performed through (gap) between each floor panel. Therefore, in particular, when a floor panel made by attaching a carpet to the surface of the panel body is laid, as the air moves, as shown in FIG. Are gradually soaked and accumulated, and stains a are generated in a grid pattern on the entire floor. Moreover, when the carpet 32 is displaced from the panel body 31 as shown in FIG. 3B, it looks like a grid pattern. There was a problem that spot-like stain b was generated on the surface.

[0003]

SUMMARY OF THE INVENTION The present invention has been made in view of such a conventional problem, and the movement of air between the room and the underfloor space of the free access floor is caused by the movement of each floor panel and the floor panel. Between floors (gap), resulting in a free-access floor that does not have the line or dot stains of conventional floor panels when carpet floor panels are used. It is something to do.

[0004]

The free access floor of the present invention which achieves such an object is a support in which a plurality of floor panels formed by adhering carpets to the surface of a panel body are erected on a foundation floor surface. A free access floor constructed by erection across legs, in which a ventilation hole communicating with the underfloor space of the free access floor is formed at any one or more places on the free access floor by hollowing out the carpet and the panel body. It is characterized by laying panels. At this time, it is preferable to install a perforated plate in the vent hole.

[0005]

[Function] When air moves between the room and the underfloor space of the free access floor due to changes in temperature, the use of vacuum cleaners, ventilation fans, etc., the movement of the air can be done at any one or more floor panels. Will be done through the vents.

[0006]

Embodiments of the present invention will be described below with reference to the drawings. The free access floor according to the present invention is basically constructed by laying and laying a plurality of floor panels 3 and 3'over the supporting legs 2 which are erected at equal intervals on the foundation floor surface 1 as in the conventional case. Be built.

In the floor panel 3, a carpet 32 of the same size is integrally attached to the surface of a panel body 31 made of die cast or steel formed in a rectangular shape such as a square of a predetermined size with an adhesive or the like. Formed.

The floor panel 3'has a carpet 32 integrally attached to the surface of a panel body 31 similar to the floor panel 3 described above, and also has a vent hole 5 communicating with the underfloor space 4 of the free access floor. I will do it.

The ventilation hole 5 is formed by hollowing out the carpet 32 and the panel body 31 into a round shape or a square shape so as to communicate with the underfloor space 4 of the free access floor from the room. The opening position, the size, the shape, the number, and the like of the vent holes 5 are arbitrary as long as the strength of the floor panel 3'is not impaired. Incidentally, one vent hole 5 in the illustrated embodiment is formed in a circular shape having a diameter of 100 mm at the center position of the floor panel 3 '.

Further, it is preferable to install a perforated plate 6 in the vent hole 5. At this time, as shown in FIG. 2, it is preferable that the surface of the carpet 32 and the surface of the eyelet 6 are flush with each other.

Then, the floor panel 3'is arranged and laid at one or more arbitrary positions on the free access floor. That is, the movement of the air occurring between the underfloor space 4 of the free access floor constructed by laying a plurality of floor panels 3 and the room is performed efficiently and smoothly through the ventilation holes 5 of the floor panel 3 ′. According to the size of the free access floor, floor panels 3'are arranged and laid at one or more arbitrary places.

[0012]

Since the free access floor of the present invention is constructed in this way, when air moves between the room and the underfloor space of the free access floor due to changes in temperature or the use of a ventilation fan, etc. The movement is performed not through the space between the floor panels (gap) but through the ventilation holes of the floor panels laid at one or more arbitrary places. As a result, even when a floor panel formed by adhering a carpet is used, there is no possibility that the peripheral edge of the carpet of each floor panel will be smeared in a line shape or a dot shape as in the conventional case.

Moreover, by installing a perforated plate in the ventilation hole, there is no fear that dust or other objects will fall into the underfloor space from the ventilation hole, and the appearance will be improved.
